Spend a few bucks more and get a better test (i.e. an actual Family Finder).

I assume you are taking advantage of the FTDNA sale for the other tests, but you can also get a sale price now on FF.

Why?

Why should she buy another autosomal test?

An AncestryDNA kit has a lot fewer SNP's and some different ones than FF. On the Family Finder database, an AncestryDNA transfer other than the original AncestryDNA version, only picks up the closer matches.

Roberta Estes has addressed this question in her blog post "Testing Strategy Should I Test at Ancestry and Transfer to Family Tree DNA?"

The Family Finder test is on sale for $59 through August 31, 2018, if you choose to go that route.

Testing with each company directly is best due to number of snps that are different between each companies chip versions. Only the snps which are tested by both chip versions can be compared.

For instance,
Family Finder test approximately 700,000 SNPS.
Ancestry V2 chip (tested after may 2016) tests approximately 670,000 SNPS.
Of the 670,000 SNPS tested by Ancestry only approximately 426,000 can be used by FTDNA (Overlap between chip versions)
That is around only 60 percent coverage.
This does not effect immediate to 2nd cousins but it does for more distant one. FTDNA only gives these transfers partial match lists. More distant matches are omitted (4th to remote category)

This also the reason new 23andme tests are no longer transferable, they only have an overlap of around 160,000 SNPS. 23 percent coverage. FTDNA deems this 23andme chip version incompatible.

As for posts about the mapmy23 tool and ancestry files that need converted. It is not that big of difference between the original ancestryV2 file and these smaller ancestry files. This smaller ancestry files or missing approximately 10000 snps which tool inserts as no calls. This is very minor when they are spread out over the 23 chromosomes . One would not notice any difference between the converted file or persons file if it was not missing snps that had actual tested values.

I do agree that ordering family finder is better then transferring but it is not always in one's budget. It also depends on if you want to see the more distant matches.

I double-checked - and also see that
http://www.mapmy23.com
now just goes to a pretty logo/picture.

That did not used to be the case. Clearly, something is going on. My recommendation, given this change and warnings you ran into when you tried to use what you found by googling --
Do not use what you found by googling.
